combinations, constructions, and arrange ments herein described and claimed.

Anobject of my invention is to provide a window construction having glass carrying sashes slidable vertically in an ordinary manner and also arranged to be revolvable at will in either raised or lowered position to permit cleaning both sides of the window without danger or inconvenience to the operative. v

A further object of myinvention is to provide a device of the type described that has means for rendering the same weatherproof.

A further object of my invention is to provide in a device of the type described a sash construction that can be used with win dow frames of an ordinary construction without the necessity of changing the con struction of the latter.

A further object of my invention is to provide a device of the type described that is simple in construction, .not likely to get out of order easily, relatively inexpensive to manufacture, and thoroughly practical commercially.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Fig. and application of the prefe'rre the device, I

Figure 8 is an enlarged detail of a fragmentary portion of the structure shown in Figure 2. v

I am aware that a reversible window broadly is not new. i

Referring now to the drawings in which the same reference numerals are used for the.

same parts throughout the views, it will be noted that I show in Fig. 1 an ordinary window frame construction in which the fixed outer side frame members are denoted by l, the top by 2, and the sill by 8. Inner side frame members 4; are spaced from the outer side frame members 1 by vertical members 5 and 6, thereby providing a com} partment 7 at each side of the window for housing counterweights 8. The vertical members 6, which as well as the members 5, are disposed at right angles to the outer side members 1, are extended inwardly, as best seen in Fig. 3. Vertical weather strips 9 are secured to the outer side of the vertical members 6 in close contact with the projecting portionof a wall 10. Strips ll of molding or the like are also secured to the outer side of members 6 in contact with the inner edge of the weather strips 9, as shown. Vertically disposed pieces of molding 12 -may he provided to cover the inner edges of the outer side frame members 1 and the members 5.

Vertical spacing bars 13 have a portion disposed in grooves 14 in the inner sides of the inner fixed side frame members f to form with the projecting ends of the members 6 a guideway 15 for the reception of a slidable sash. Additional vertical spacing members 16 are secured to the inner side frame member 4 to provide with the spacing bars 13 a second guideway 17 for'the reception of an additional slidable sash. The

par-ts described so far are ordinary in construction and form no part of my invention except in so far as they cooperate with the parts about to be described.

In the ordinary window construction the upper sash is slidably disposed in the guideway 15 which is the outer of the two guide ways, while the lower sash is slidably disposed in the guideway 17.

In carrying out myinvention, I provide a sash carrying casing 18 that is slidably disposed in the guideway 15. The sash carrying casing is formed with vertical channels 19 in its side members for the reception of sash cords 20 each of which has one end secured thereto in an ordinary manner and has its other end secured to one of a pair of couterweights 8. Each sash cord. 20-extends upwardly and is guided by a pulley or sheave 21 that is journalled in one of the inner side frame members 4 adjacent the. upper end thereof.

Channels 22, arranged to face each other, are secured to the inner edge of the members 6 (see Figures 3 and 6). A dummy sash 23, which has its side members reduced at 24 to enter the channel guideways 26, is slidable vertically therealong. Y

The slidable movement of the dummy sash 23 is controlled by a plunger 27 formed with side arms 28 having a roller 29 journalled at 30 therebetween, since this plunger which is disposed in. an opening 31 extending inwardlyfrom each side edge of the sidewalls 8 which are connected to the side members of the dummysash 23 is pressed outwardl by the action of a compression spring 32. rolling contact is thereby established with the inner wall of the channel 22, whereby the dummy sash 23 will be maintained in any position along the channel guideway and may be movedslidably therealong at will. I also provide means for locking the dummy sash 23 in its raised or lowered position,

such means consisting of a lock 33 preferably of a flush bolt type disposed in a recess 34- in the side member of the dummy sash 23 and provided with a bolt 35 that can be moved selectively into or withdrawn from a slot .36 provided throughthe channel 22 intermediate its length into the member 6 or a similarslot 37 through the channel 22 into the member 6 adjacent the lowerend thereof.

. The slidable movement of the sash carrier 18 is controlled by one pair of the counterwelghts 8, as stated. A glass holding sash 38, which is suitable in size to fit within the sash carrying frame 18, is provided with. plates 39 countersunk in horizontally alined' recesses 40 in its side edges. These plates 39 have projecting studs 41 which may he moved into socket-s 12 formed in plates 43 secured to the edges of the side walls of the 1 sash carrying casing 18 through upwardly extending side slots 44:, whereby the casing 38 is revolvably supported by the sashcarrying casing 18. The glass holding sash 38 is provided with a locking device 45 having w a bolt 4C6v positioned-to be moved selectively into one of theslots .427 and 48 provided inthe top and bottom members ofthe. sashcarrying casing'l8 to prevent the glass holding sash being revolved and. to maintain, the

I same in a verticalposition, as pictured. in

Fig. 1 of the drawings.

It will be understood that the dummy sash 23 and the sash carrying casing 18 in which the glass holding sash 38 is mounted form what is normally the upper half of a twosash window. A. second spacing member 49 is secured to each of the spacing members 13, as shown in Fig. 3 of the drawings, and channels 50, which are precisely identical with the channels 22 are secured to the members l3 and the spacing members 49 to'provide a channel guideway for a second dummy sash 51. parts appurtenant thereto are precisely identical in essential respectswith the dummy sash 23 and consequently need not be described in detail. Corresponding precisely identical parts inthe dummy sash23 and the dummy sash 51 aswell as any parts connected thereto have'been designated by the same reterence numerals.

Adjacent the dummy sash 51 is a second sash carrying casing 52 that is slidably disposed in guideway 17, The slidable movement of the sash carrying casing 52 is controlled by a second pair of counterweight-s ber-4L9, being wider than the similarslot 19;

in the sides of the sash carrying casing 18, since the provision of they spacing member 49 positions the sash carrying casing 52 slightly farther from the center spacing bars13 thanis ordinary. Consequently, the

The dummy sash 51 and the,

slot 55 musthe widenedto accommodate the v pulley 54- and to insure freemovement of the sash {cord 53 therein.

A second glass holding sash 56 is mounted in the sash carrying casing 52 in the same manner as the glass-holding sash 38 is mounted in the sash carrying casinglS.

From' the forego g description of various parts of the device, the operation thereof may be readily understood. The

sides and the top and the bottom of the.

dummy sashes 23 and 51 extend inwardly beyond the inner edges of the sash carrying.

casings 18 and 52 respectively. Consequently, a. window having this construction is thoroughly waterproof. The glass holding sashes :38 and 56 may be revolved-at will to reverse the same when the dummy sashes have-beenmoved vertically out of-the way.

Cleaning of both sidesthereof by an open.

ator standing within the room provided with myimproved window construction maybe accomplished; The glass holding sash 56 is provided With'locking means for mainraa'zgeesa taining the same in vertical position when desired. Such locking means are precisely identical withthose described for the glass holding sash-38 and have been denoted by the same'reference numerals.--.The dummysash 23 may be lowered orraised at will independently ot the sash carrying casing. 18. In other words either one of the pairs of dummy sashes and sash carrying casings may be raised or lowered independently of each other andeach elementmay be raised and lowered independently of the other elements in the sets of dummy sashes and sash carrying casings.

The glass holding sashes may be revolved in either raised or lowered position and may be partly revolved for ventilating purposes, if desired. 1 also provide means for locking one sash carrying casing in uppermost position, while the other set of dummy sash and sash carrying casing is located in lowered position. Such means comprise a pin 57 that can be projected through alined keepers 58 and 59 that are secured to the upper sides of the dummy sash 51 and the sash carrying casing 52. The end oi. the pin or bolt 57 extends within a recess 60 in the bottom member of the sash carrying casing 18, wherefore the parts of the device are locked in the position pictured in Fig. 2 of the drawings. The pin or bolt 57 is formed with a groove or slot 61. adapted to receive a finger 62 depending from the keeper 59, wherefore the pin or bolt 57 can not be entirely withdrawn from the keeper 59.

It is obvious that the device described may be converted into a weightless window without departing from the spirit and scope of the invention. since automatic spring pressed frictional means (not shown) may be dis posed between the sides of the sash carrying casings 1S and 52 and the inner sides or the frame. I

One of the advantages of the device lies in the ttactthat the glass holding sashes may be instantly removed from the sash carrying :trames for any purpose whatsoever and as quickly replaced without it being necessary to use any tools in accomplishing the removal. This is possible, since the glass hold ing sashes are maintained by their own weight in pivotal relation with the sash carrying frames when the studs ll have been moved into the sockets 42 through the upwardly inclined communicating slots 414 that are open at their upper ends.
